That was exactly my point... she DIDN'T know there was a lineup change.

Now, I don't know how many opening gigs they did, but they did that one. That is the situation I was talking about. I did say this was on the REO board and she saw them with REO. When a band plays on the same bill as another band (as an opening band or in some other arrangement) you will have folks there that would not have gone to that band if that band played by themselves, but who have an impression of the band based on the records they have heard on the radio. It is this sort of casual fan that I am talking about.
